(Structure of fiber assembly)

Further, the fiber assembly 111b is a single fiber structure composed of fibers, or a fiber structure in which fibers are gathered in the longitudinal direction and/or the radial direction (crepe, spinning, a plurality of long fibers are partially or joined) The yarn material or the like, or an aggregate of the fiber structure, may be composed of a fiber assembly in which a thermoplastic fiber is contained and melted (also referred to as "welding"). The fiber forming the fiber assembly 111b is a structural unit of a yarn, a woven fabric, or the like, and is defined as a finer and more flexible shape having a sufficient length than the thickness. A typical example is a long continuous fiber as a long length. Filament, short fibers as staples. The fiber structure base end side of the fiber assembly 111b is joined by the fusion bonded portion 113 and the fusion bonded portions 114, 114, and the fusion bonded portion is used as a fixed end, and is opposed to the fixed end. The side (front end side) as a free end extends in a long shape in a direction crossing the long axis direction of the cleaning body 110 (or the fiber assembly 111b). This fiber assembly 111b is also referred to as a "fiber bundle" in which a plurality of fibers form a bundle.

Furthermore, in the example shown in FIG. 9, the case where the fiber aggregate 111b is formed by laminating three fiber layers in a laminated form is described, but the number of the fiber layers may be one or plural as needed. One. The fiber assembly 111b has a surface structure composed of a predetermined plane, a curved surface, or the like, and is preferably formed into a three-dimensional shape having a certain thickness or a thin sheet shape. The "fiber aggregate" referred to herein is typically made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon, or snail. In the above, a plurality of aggregates of filaments obtained by opening a tow are used as the aggregate of fibers. In particular, the fiber assembly is composed of a composite fiber in which the core portion is polypropylene (PP) or polyethylene terephthalate (PET) and the outer sheath portion of the core portion is polyethylene (PE). good. Further, each of the fiber assemblies may be formed of fibers having substantially the same fineness, or may have a structure in which fibers of different densities are included in each of the fiber assemblies.

Moreover, in order to improve the sweeping function at the time of cleaning, it is preferable to use a fiber aggregate including fibers having high rigidity, that is, fibers having high fineness. Further, the fiber assembly system is preferably a structure having crimped fibers. The crimped fiber referred to herein is configured to impart a fiber having a predetermined crimping treatment, which is a structure in which fibers are easily entangled with each other. When such a crimped fiber is used, the fiber assembly becomes more bulky than the state before the cleaning body is installed, and it is easier to trap the garbage in the structure of the crimped portion. This structure can be realized in particular by crimping fibers formed using tow fibers.

Further, as the fiber assembly, a thermoplastic film resin called a flat yarn or a tear yarn which is formed by cutting a film into a strip shape and extending in the longitudinal direction may be separated in a direction orthogonal to the orientation direction of the resin, and The fibrous film is joined in the form of a mesh. Alternatively, as the fiber assembly, a non-woven fabric having a high bulkiness and a low fiber density such as a hot air non-woven fabric may be used.
